Major Retailer Shifts Nuclear Strategy
In a surprising move that underscores the evolving landscape of corporate energy procurement, Walmart has signed a long-term power purchase agreement (PPA) with Constellation for emissions-free electricity from the Dresden Clean Energy Center in Morris, Illinois. Announced in June, the deal includes approximately 176 MW of wholesale supply, 30 MW of which comes from expanded generating capacity through efficiency upgrades known as uprates.
First-of-Its-Kind Agreement for a Large Retailer
This marks Walmart’s first nuclear PPA and is among the first such agreements between a large retailer and a nuclear energy facility in the United States. The 15-year terms commence in 2029 and 2030, providing Walmart with energy, environmental attributes, and capacity. The agreement supports reliable nuclear energy in the region and enables planned uprates—efficiency upgrades that increase output from existing nuclear units without building new facilities.
Supporting Local Infrastructure and Jobs
The power generated will help support Walmart’s high-tech perishable distribution center currently under development in Belvidere, Illinois. Jim McHugh, Senior Executive Vice President and Chief Commercial Officer of Constellation, stated: ‘This agreement reflects long‑term stewardship of critical infrastructure, the communities it serves, and the energy system that powers American growth. Walmart’s commitment enables meaningful investment in the Dresden Clean Energy Center—bolstering reliability, sustaining local jobs and economic activity, and putting more dependable, emissions-free energy onto the Illinois power grid.’
While the press release notes that new nuclear construction is the most expensive option for new power capacity, leveraging an existing plant for increased CO2-free electricity is a pragmatic and cost-effective path for Walmart to access cleaner energy while maintaining everyday low prices.
